Mechanical Advantage is given by the following equation: MA = Load Effort On a class 2 lever, the fulcrum (pivot) is at one end of the lever and the work applied is at the other end. The load is then applied near the fulcrum, as common with the wheel barrow. A class 3 lever has the effort applied between the fulcrum and the resistance. Therefore, a much greater effort will be required to produce the same moment value. A typical C2 lever has a much greater distance in which to produce the load than a C3 lever.
Yes, a hammer can be both a class-1 and a class-3 lever. Although, not all levers can be more than one class only some. For example, a hammer and a clothespin.
class one lever is a seesaw
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
Why a third class lever cannot magnify force
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.

A lever with a mechanical advantage greater than one is used to increase distance. A lever is a simple machine connected to ground by a hinge called a fulcrum.

A see-saw is a fulcrum type of lever.
a class two lever has fulcrum at one end and the load in center
Class one lever.
